System-specific DDR3L kit for 27-inch iMac 2015
This 8 GB kit contains two 4 GB SO-DIMMs built to the DDR3L 1600 standard with CL11 timing and 1.35 V operation. It targets owners of the Mid 2015 Retina 5K iMac (MF886LL/A) who want a matched pair for the factory slots. The modules are unbuffered, non-ECC and use a major-brand chipset for reliable operation.
Matched pair eliminates mixed-module uncertainty
Supplied as a 2-piece kit, the sticks share identical speed, latency and voltage ratings so the memory controller sees a uniform configuration. This removes the timing mismatches that can occur when adding a single module to an existing stick of different origin. The package includes only the two SO-DIMMs; no tools or software are bundled.
204-pin SO-DIMM form factor fits the iMac's
Each module uses the standard 204-pin DDR3 SO-DIMM edge connector with no heat spreader, keeping the profile low enough for the tight SO-DIMM bays in the 27-inch chassis. The system provides four sockets with a 32 GB ceiling, so this 8 GB kit leaves room for future expansion. Buyers needing more than 32 GB total or requiring registered ECC modules should look elsewhere.

Questions about this item
Will the 1Rx8 DDR3L modules ever need replacement under normal desktop use?
The 1.35 V DDR3L 1600 sticks carry a limited lifetime warranty from Computer Memory Solutions, so they are not expected to require scheduled replacement.
What limit appears first when the iMac 27-inch Mid 2015 runs sustained loads with this 8 GB kit?
The 8 GB total capacity (2 × 4 GB) will fill before the CL11 DDR3L 1600 speed becomes a bottleneck on the MF886LL/A.
How much heat and power do the unbuffered 1.35 V SO-DIMMs add during all-day operation?
At 1.35 V the DDR3L modules draw less power and generate less heat than standard 1.5 V DDR3, keeping thermal load low in the 27-inch 2015 iMac.
